Hi,
repairing a benq. This works but make noise like frying and the backlight sometimes flashes to full bright. If the fry increase the screen may become black with power led remaining on and i have to power off and on again. The board is toasted on the point where seats the two LR3410 (expecially the upper one) that drive the only two inverter transformer. Caps checked, transformer's and others joints resoldered.
I think i should change the LR3410 but i can't find them. Do you know an equivalent?
Thanks.
